Working Principle

The DSC1001DC5-024.5760T oscillator is a CMOS voltage controlled oscillator, making use of electromechanical and piezoelectric techniques for frequency tuning. The oscillator utilizes a tuned circuit comprised of a quartz resonator and an integrated capacitor, as well as an active transistor for direct current amplification. The quartz resonator is a small quartz crystal which vibrates at a frequency of 32khz when an alternating current signal is applied. This alternating current signal generated by the quartz resonator is amplified by the active transistor, and then fed into the integrated capacitor.

The capacitor acts as a feedback signal, allowing the oscillator to self-regulate its frequency. The frequency can be adjusted by adjusting the voltage driving the active transistor. The frequency of the oscillator is set by the resistor in the active transistor, producing the desired output frequency.
